Answer:

The angle made by line with positive x axis is more than 90°

Step-by-step explanation:

A line is represented in slope intercept form as

y=mx+c

Where m is called the slope of the line and c is called the y intercept .

Here by slope we means the tangent of the angle , the line makes with the positive x axis .

Now in the case when the coefficient of x is negative , that means the tangent of the angle which line makes with the positive direction of x axis is negative

or

tan \theta = negative

\theta > 90

that means our line makes an obtuse angle that is more than 90° with the positive x axis.

A boat can travel 23mph in still water. If it travels 248 miles with the current in the same length of time it travels 120 miles
mixas84 [53]

Answer: the speed of the current is 8 mph.

Step-by-step explanation:

Let represent the speed of the current

boat can travel 23mph in still water. This means that the total speed with which the boat travelled is (23 + x) mph.

Time = distance/speed

If it travels 248 miles with the current, it means that the time it took the boat to travel with the current is

248/(23 + x)

in the same length of time it travels 120 miles against the current. This means that the total speed with which the boat travelled is (23 - x) mph. The time it took the boat to travel against the current is

120/(23 - x)

Since the time is the same, it means that

248/(23 + x) = 120/(23 - x)

Cross multiplying, it becomes

248(23 - x) = 120(23 + x)

5704 - 248x = 2760 + 120x

120x + 248x = 5704 - 2760

368x = 2944

x = 2944/368

x = 8 mph

The first inverse operation you would use to solve the equation 2+5x= -8 for x is subtraction. true or false?
jok3333 [9.3K]

Answer:

It would be True

Step-by-step explanation:

2+5x = -8

SUBTACT 2 on both sides and it would look like this:

5x = -8 - (2)

5X= -10

then DIVIDE 5 both side to get "X" ALONE,

x= -10/5

then divide -10 with 5

equal to:

x = -2
